摘　　要：目的:评价开窗减压术在治疗含牙囊肿(DC)、牙源性角化囊性瘤(KTOC)和单囊型成釉细胞瘤(UAB)的疗效和影响囊肿愈合的因素。方法:纳入30名牙源性颌骨囊性病变患者,包括5例DC、13例KTOC和12例UAB,均行开窗减压术,术后佩戴囊肿塞进行治疗,对术前、术后患者的CBCT影像进行分析。结果:3种颌骨囊性病变的相对缩小面积均随时间的增加而增加,DC(r=0. 124,P=0. 843),KTOC(r=0. 634,P=0. 002),UAB(r=0. 726,P=0. 008)。DC(10. 77%/月)与KTOC(5. 59%/月)和UAB(5. 52%/月)的相对愈合速度比较有统计学意义(P <0. 05)。KTOC(r=0. 787,P=0. 001)和UAB(r=0. 766,P=0. 004)的绝对缩小速度与原始囊腔大小均有显著相关性; UAB(r=-0. 629,P=0. 028)的相对缩小速度与患者年龄相关性显著。结论:开窗减压术是治疗牙源性颌骨囊性病变的有效方法,术后DC比KTOC和UAB的愈合速度要快,患者年龄和原始囊腔大小对囊肿的愈合速度有一定的影响。Objective:To evaluate the clinical effectiveness of decompression as the primary treatment of odontogenic cystic lesions of the jaw and related factors.Methods:30 patients with odontogenic cystic lesions of the jaw underwent decompression with customized thermoplastic resin stent,including 5 with dentigerous cyst(DC),13 with keratocystic odontogenic tumor(KTOC),and 12 with unicystic ameloblastoma(UAB).Pre-and postdecompression CBCT data were analyzed.Results:The relative speed of shrinkage of DC(10.77%/month)was faster than that of KOTC(5.59%/month)and UAB(5.52%/month).The relative shrinking size increased linearly in a time-dependent manner for DC(r=0.124,P=0.843),KTOC(r=0.634,P=0.002)and UAB(r=0.726,P=0.008).A similar relation was detected between the primary radiolucent area of cystic lesions before decompression and relative shrinking speed after decompression in KTOC(r=0.787,P=0.001)and UAB(r=0.766,P=0.004),but patient age did not affect the relative speed of shrinkage(P>0.05),except for UAB(r=-0.629,P=0.028).Conclusion:Decompression is effective in treating odontogenic cystic lesions of the jaw.The velocity of shrinkage after decompression is faster in DC than in KTOC and UAB.The age of the patient and the initial size of the lesion may effect the speed of healing.
